What to know before buying

The listing says the cable must be installed in the correct direction, with its source end connected to the player or console and its display end to the TV or projector. It claims no external power is needed.

Listing details to confirm

Listing details are inconsistent or unconfirmed: the 144 hertz frequency field does not specify a resolution, while separate claims pair 2K with 144 fps and 4K with 60 fps. Confirm that the intended source, display and resolution/refresh-rate combination match before buying. The 18 Gbps figure and advertised signal-loss wording are listing claims, not independently verified performance.

Who is it for?

A good fit for

People routing HDMI over a long indoor distance to a television, monitor or projector.
Installations where a thin, flexible cable and reduced susceptibility to electromagnetic interference are useful.

Less suited to

Buyers who need a cable for outdoor use, which is not the listed application.
Anyone needing confirmed support for video modes beyond the listing's 4K at 60 fps and 2K at 144 fps claims.

Aggregate ratings lean positive overall, but a substantial share are lower-star ratings, so experiences are not uniformly favourable. Without written feedback, the ratings do not show what customers liked or disliked. For a 30 m cable with directional installation and specific resolution claims, buyers should verify their setup requirements rather than treating the rating as evidence of compatibility.
